I linked my account about a year ago when the COH-Dev stuff started to play the Betas, I did not receive the 30k supply and never got a email about it. I made sure my email for Steam and Relic are the same. I can't find any tech support page about this issue so I hope posting here someone will help me get it or tell me that the 30k for linking ended last year or something.
